File: 75 KB, 1646x666, sum of two convex functions.jpg [View same] [iqdb] [saucenao] [google]

Can anyone help me with this? The use of the theorem that the sum of two convex functions is convex was required for an exercise for a calculus exam but the demonstration isn't in the book, it was left as an exercise to the reader lol. But unless I am doing something very stupid, it seems that I found a counter-example? In the pic w and g are convex, but w+g isn't?
